Answer 1

①I think the old brushes[are useless].(对中括号部分提问）
我觉得这些旧刷子没什么用处。
What do you think of the old brushes?
你觉得这些旧刷子怎么样？

②Something is wrong with your computer,( isn't it )?(完成反义疑问句）
（No, it isn't ）.(做否定回答）

陈述部分主语是指示代词或不定代词everything, something, that, nothing, this, 疑问部分主语用it。 所以填isn't it

回答反意疑问句和回答一般疑问句一样,肯定回答用"Yes, +肯定结构";否定回答用"No, +否定结构"。这与汉语习惯有所不同。例如:

-He's a doctor, isn't he?他是医生,对吧?

-Yes, he is.对,他是医生。(No, he isn't.不,他不是医生。)

所以此处应为：--你的电脑有故障了，不是吗？--不是，我的电脑没有故障。

③Those houses were dangerous.we had to ( take ) ( them ) ( down ).(把他们拆除）

Take down
拆除，记下
I take down the booth.
我拆除了摊位。
